Located just outside the city of Brownsville, Palo Alto Battlefield NHS was established to preserve the site of an important battle between American and Mexican troops in 1846. Plenty of information about the battle and about the Mexican War in general can be found in the Visitor Center, which offers interactive exhibits, a collection of historical artifacts and military uniforms, and the opportunity to watch a short film. The park is open year-round, but the best time to visit is between December and March, as this is when special guided programs are offered.
